i like this OP
this is exactly my experience, (perhaps to a slightly lesser extent), but i live in a city in england which is ~~ 50% white british, ~~ 40% pakistani / south asian and ~~ 10% eastern european
throughout my entire life i've seen/heard massively disturbing things relating to race, i've heard of gangs of white guys going "paki bashing", "friend hunting", my dad was held over a cliff when he was 12 by a group of pakistani guys because my uncle beat up one of their friends, etc etc, basically just mass violence and hate related to race
so as OP says, when i see a lot of people on the internet; many of whom are ~~ 15-20 years old, no real life experience, many living completely sheltered lives, using these amazingly racist terms (constantly saying jew as derogatory, my old friend, friend, etc etc), it really does shock me
the point is you should watch what you say, one day you might actually meet that black/jewish/gay guy who's member of family was actually raped and murdered by KKK / neo chocolate chip cookies, and it might all come home to you what you're actually saying
